T 0 all whom z't may concern.

Be it known that I, JOHN EDWARD ABLER, a citizen of the United States ofAmerica, and a resident of the city of Guelph, in the county oflVellington, in the Province of Ontario, Canada, have invented certainnew and useful Improvements in Screw Sockets for the Necks of FlexibleContainers, of which the following is the specification.

My invention relates to improvements in filler sockets for rubber orcompound containers, and the object of the invention is to devise simplemeans which will absolutely prevent the turning of the socket in theneck of the container or prevent it becoming loose owing to the heatingof the material by the hot water in the container, and it consistsessentially of a metal screw socket and means forming projectionsextending from the periphery of the socket and connected thereto andembedded in the material so as to form a secure lock, preventing theturning of the socket within the neck, all as hereafter moreparticularly described.

Fig. 1 is a perspective view of the neck portion of a flexiblecontainer, the wall of the neck being broken away to exhibit my socket.

Fig. 2 is an enlarged cross sectional view through the socket neck andmy locking device.

Fig. 3 is a plan sectional view on line 33, Fig. 2.

Fig. 4 is an enlarged perspective detail of my locking member as itappears before being connected to the socket.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 indicates the neck of a flexible container. 2 indicates the socketwhich is secured in the neck of the container.

3 is a plate which is annular in form, the central orifice of which isturned up into an annular flange 5 and spun into the bottom orifice 2*of the socket. The plate 5 is provided with a series of radiating arms 6which are bent upward parallel with the face of the socket wall, and inwhich a series of inwardly extending projections 7 are formed either bypunching in the metal or by any other suitable means. Softened rubber orother compound is run around the socket so as to flow in between thearms 6 and the wall of the socket, the projection 7 forming spacingmeans and permitting the material to flow freely into the interspace.

The socket is then inserted in the neck of the container and vulcanizedtherein, the plate 3 being spun into the bottom orifice, and the socketsecurely holds such plate in position so that the socket cannot turn inthe surrounding material, and the arms 6 extending upward parallel tothe walls of the socket, forming projections or ribs embedded in thematerial extending between the socket and the outer face of thecontainer neck, absolutely preventing the turning of the socket withinthe material.

That I claim as my invention is:

1. In a container formed of flexible material or compound, thecombination with the neck and screw socket, of means extendinglongitudinally of and from end to end of the socket and in spacedrelation thereto for preventing its turning within the neck of thecontainer.

2. In a container formed of flexible material or compound, thecombination with the. neck and socket, of an annular member engagingconcentrically with the lower end of the socket, ribs extendinglongitudinally of the socket and carried by such annular member at oneend so as to be in spaced relation to the outer periphery of the socketand embedded in the material located between the exterior periphery ofthe socket and the neck of the container.

3. In a container formed of flexible material or compound, thecombination with the neck and the socket inserted in the neck, of stripsextending vertically of the socket adjacent its exterior surface, meansfor securing the strips in position in relation to the socket, andprojections extending inwardly from the inner face of the strips forspacing said strips from the surface of the socket.

4. In a container formed of flexible mate: rial or compound, thecombination with the neck and socket, of an annular plate having itsinner edge spun upward into the central bottom orifice of the socket andhaving fingers extending from its outer periphery adapted to be bent upxard against the exterior wall of the socket and to be embedded in therubber and located between the exterior face of the socket and theexterior face of the bottle neck.

5. In a device of the class described, a socket locking membercomprising an annular plate adapted to be secured at its inner peripheryto the bottom of the socket, and provided With radial fingers extendingoutwardly therefrom, adapted to be bent iup- Ward against the exteriorsurface of the socket.

6. In a device of the c1as s described, a socket locking membercomprislng an annular plate adapted tobe secured at its lnner peripheryto the bottom of the socket and provided with radial fingers extendingoutwardly therefrom adapted to be bent up- Ward against the exteriorsurface of the socket, and projections extending inwardly from thefingers spacing the fingers from the exterior surface of the socket.

JOHN EDWARD ABLER.
